Unzip the files to a directory included in your MATLAB PATH setting.

Submit Functions for MATLAB R2012a -(updated ).

The functions are written in MATLAB making them cross-platform and only dependent on the version of MATLAB in use. These directories on the respective operating systems are listed below.Īll operating systems (Windows, Linux and Mac) are supported by the same set of submit functions. The easiest way to accomplish this is to copy the submit functions to the default directory created for by MATLAB. These submit functions must be installed on your computer and must be accessible to MATLAB via the MATLAB PATH environment.

The MATLAB submit functions create a cluster job context for your code and are responsible for transferring your code and the data it analyzes to the cluster for processing. MATLAB DCS from Your Desktop MATLAB Submit Functions Please request an account by sending an email to ] and include your campus affiliation and a brief statement of your research interests for using the cluster. Using MATLAB DCS requires you have a cluster account on Cheaha. For DCS configuration instructions on previous versions of MATLAB, please see the page MatLab DCS R2010a and Earlier or Matlab DCS R2010b -R2011b This page documents the DCS configuration for MATLAB 2012a and later.

run the validation tests to confirm a working installation.

configure the "cheaha" parallel computing target to which PCT tasks can be submitted.

Once your tasks are submitted to Cheaha, your desktop MATLAB is also free to move on to other tasks or be closed completely, freeing your desktop or laptop for your other activities.Ĭonfiguring the Parallel Computing Toolbox involves three steps documented below: This makes the expanded compute power of Cheaha available to processes work loads that exceed the capabilities of your desktop computer. The PCT allows MATLAB running on your workstation to send MATLAB code and data (tasks) to the cluster directly from the comfort of your familiar MATLAB environment on your desktop. The MATLAB Distributed Computing Services (DCS) are accessed via the Parallel Computing Toolbox (PCT) which is installed as part of your desktop MATLAB installation. When you are finished with your job contexts, clean up the job related content to free disk space.Use your workstation MatLab application to retrieve the results.You will receive an email when the tasks you submitted are complete.Note: your workstation MatLab application does not need to keep running after the tasks are submitted.

Once your code works, select the "cheaha" parallel configuration to submit tasks to the Cheaha cluster.

Write, test and debug your parallel code on your local workstation using the default "local" parallel configuration.

Develop and Run Parallel Computing Applications.

Run the validation tests to ensure your "cheaha" parallel configuration works.

Define the "cheaha" parallel configuration in your workstation MatLab environment to submit tasks to Cheaha.

Install MatLab with the Parallel Computing Toolbox on your Windows / Linux / Mac workstation.Configure the Task Submit Environment (One-time Setup).The following outline highlights the steps involved to configure your MatLab install and write programs that submit tasks to the worker nodes of the Distributed Computing Server on Cheaha: 2.1.2.3 Begin Using MATLAB DCS from your Desktop.2.1.2.2 Validate the "cheaha" PCT Configuration.2.1.2.1 Personalize the "cheaha" PCT Configuration.2.1.2 Parallel Computing Toolbox Configuration.Submit the job using 'qsub parallel-test.sh', assuming the name of the submission script is called parallel-test.sh. Here is a link to Matlab documentation on parfor loops: A parfor loop can be used when each iteration of the loop is independent of all other iterations. The easiest way to make a Matlab program parallel compatible is to use parfor (parallel 'for') loops. There is some overhead to running jobs in parallel, so it can be slower to run on multiple cores if the job is small without sufficiently large loops. Note that lines starting with '#$' are SGE shell commands, whereas '#' symbols denote comments, and the remaining lines are matlab commands. The following example script can be used to submit a Matlab job to SGE to run on 8 cores (you may use all the cores in a node – which may be more than 8). Information on the Parallel Toolkit may be found here. The current installation of Matlab uses the Parallel Toolbox, which allows for parallel jobs that can use up to the total number of cores per job. To get started, type one of these: helpwin, helpdesk, or demo.ĩ235 18735 22408 Parallel Matlab Jobs (or "pool jobs")
